The Fault in Our Stars is the movie—and book—people have been talking about for a while now. Getting like MAJOR buzz. And people will for sure will be talking about it for a while after this weekend , as the film opens nationwide today. But what's the hype about? We break it down for you five ways.

2. The book is really successful and really good, too: The John Green story—the author has been called "The Teen Whisperer"—has been on the New York Times's best-seller list for 124 consecutive weeks and on top of that, it reached the No. 1 spot on Amazon six months before it was even published.

3. It's a cancer love story, but not in the "usual cancer love story" sorta way: Green set out to write an "unsentimental" cancer novel, and the film has stayed true to that desire, with smart, fresh dialogue ("What a slut time is. She screws everybody."), and characters that are fleshed out, but still come off as real people.

4. It's an epic romance: You're going to cry. Just accept that now. But there's no time like the summer to indulge in a sweeping love story, right? And this one's for the record books, guys. Even the cast has admitted to crying.

5. The soundtrack is awesome: Ed Sheeran, M83, Lykke Li, Birdy, and many more contributed sweet tracks (see it here). So at least there are some really good tunes to accompany those tears.
